T 0 all whom it may concern:

Be it known that I, SAMUEL FURRY,

a citizen of the United States, residing at paving and.it is the principal object of the,

invention to provide a novel form of approach for use 1n connectlon with bridges whereby to eliminate the jolting of a vehicle moving thereover and also reducing the pull or draft to minimum by reason of the gradual and even grade afforded thereby.

Another and equally important object of the invention is to provide a bridge approach which is of such construction as will render the same exceedingly strong and durable; hence, preventing excessive wearing thereof and the washing out of portions of the same by reason of the flow of water thereover and also, affording an effectual hold for' the feet of draft animals passing thereover.

The invention consists, furthermore, in the novel combinations of parts of the approach, as well as in the details of construction of the same, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claim which are appended to this specification and which form an essential part of the same.

In the drawings:

Figure 1 is a top plan of theimproved approach, a portion of which is broken away.

F ig. 2 is a similar view of a slightly modified form of approach,

Fig. 3 is a longitudinal section taken on the line 33 of Fig. 1, and

Fig. 4 is a similar view taken on the line 4l-4 of Fig. 2.

Having more particular reference to the drawings, in connection with which like ref erence characters W1ll designate correspond- 1 ing parts throughout the several views, 1 designates a portion of the bridge to which the improved approach is applied and 2 the roadway communicating therewith, which roadway, as will be noted, is formed with a rise 3. the purpose of which will be presently apparent.

A portion of the rise 3 is removed and is filled with a plastic, preferably concrete,

bed 4, the lower end of which is curved or off-set as at 5 to provlde a drain or gutter extending transversely of the same and into which gravel or loose rock 6 is placed. In

this connection, it will be noted that a portion of the exposed surface of the bed is corrugated at T and is arranged flush with the surface of the adj oining portion of the rise 3, thus, enabling the vehicle to move easily thereover'; the corrugations 7 serving to provide an effectual foot hold for draft animals and as a non-skid surface for the wheels of the vehicles passing thereover.

Embedded in the bed 4 of the approach 6 is a corrugated metal sheet 8 formed with a plurality of perforations generally indicated by the numeral 9, whereby to permit passage of the concrete therethrough and resultant tying or binding of the same therein. The lower end of the reinforce is bent upon itself as at 10 to conform in shape to the curved portion 5, while the upper or remaining end thereof is extended into the plastic material from which the bridge flooring is constructed, as indicated by the reference numeral 11. In this way, undue movement of thereinforcement'with relation to the brid e flooring will be positively prevented and further, disconnection of the same from the bridge and the resultant rut will be prevented.

"*In the Figs. 2 and 4, I have illustrated a son of the mode of engagement of the rein-- forcement 12 with the bridge, it will be readily understood that the expansion and contraction of the approach and the b idge are provided for.

Itmay be here noted, that the corrugations formedin'the exposed surfaces of the approach bed -i indicated by the numeral 7, and the corrugations formed in the rcin forcement 12 are substantially V--Sll:ll)((l and as a consequence. insure the propcr drainage of water therefrom.

I desire to have it understood, that the utility of the invention is not limited to the form thereof herein shown, but if desired, can be adapted for use in connection with culverts, road grades, road crossings and she s.

is hereinbefore indicated, I do not wish to be understood as confining the invention to the particular embodiments chosen for illustration herein. nor to the exact construction and arrangement and adaption of parts shown and described, but I reserve the right to niake'any changes and, alterations that fairly fall within the spirit and scope of the therewith. the lower end of said approach being formed with a transverse drain, and reinforcing means in said approach engaged with one of said ways 3. In combination with vertically disalined communicating ways, an approach arranged between the same and adjoining flush therewith, the exposed surfaceiof said approach being corrugated, and a transverse drain arranged in the lower end of said approach.

4. In combination with vertically disalined communicating ways, an approach arranged therebetween and adjoining flush therewith, a corrugated reinforce engaged with the approach, the lower end of said approach being formed with a transversely disposed drain, and means for effecting connection between one end of said reinforce and one of the ways.

5. In combination with vertically disalined communicating ways, an approach arranged therebetween' and adjoining flush therewith, a corrugated reinforcing element embedded in said approach having one end extended into engagen'ient with one of the ways,- the lower end of said approach being formed with a transversely disposed drain.
